BAROTHERM® GOLD thermally conductive grout is a bentonite material designed for use in grouting boreholes containing ground source heat loops, and related applications. BAROTHERM GOLD thermally conductive grout when combined with silica sand at various concentrations yields a grout with thermal conductivity values ranging between 0.4 and 1.2 BTU/hr·ft·°F (0.69 - 2.08 watts/m ·°C).

    The use of BAROTHERM GOLD thermally conductive grout promotes:
  • A thermally conductive grout medium with low permeability for sealing ground source heat loops

Features & Benefits:

  • Promotes efficient heat transfer
  • Produces a uniform slurry for smooth pumping - No need to add extra water
  • Creates a low permeability seal
  • Develops a permanent, flexible seal to prevent commingling between aquifers
  • No heat of hydration
  • No Portland or aluminum cement added
  • No gypsum added
  • NSF/ANSI Standard 60 Certified
